Hot-melt adhesive web film and hot-melt adhesive film are two kinds of hot-melt adhesive products that are widely used nowadays, especially in textiles, clothing, and shoe materials. Many manufacturers do not know how to choose when consulting the two hot melt adhesive web and hot melt adhesive film products, especially when comparing prices; there are many entanglements.
So, compared with hot melt adhesive web and hot melt adhesive film, which one is cheaper? Is it more cost-effective?
Whether it is a hot melt adhesive web film or a hot melt adhesive film, they are all made of hot melt adhesive particles. In essence, they are not different, but they are different in the form of hot melt adhesive products. . The hot-melt adhesive web film is formed by spinning the hot-melt adhesive particles after melting, and the hot-melt adhesive film is formed by coating or laminating after the hot-melt adhesive particles are melted. Therefore, the hot melt adhesive web is in the form of a wire web, while the hot melt adhesive film is in the form of a flat film.
When you consider whether to use a hot melt adhesive web or a hot melt adhesive film, you should first consider the performance, not the price. Because although these two products are essentially the same, in fact, there are still some differences in performance characteristics due to the difference in shape.
First of all, due to the web structure of the hot melt adhesive web, its air permeability is better than that of the flat film, but the advantage of the flat film is that its sizing is more uniform, so the uniformity of the adhesive layer is better. This helps to improve the bonding strength to a certain extent. These two points are the biggest difference between hot melt adhesive film and hot melt adhesive web film, but they are not significant.
For another example, when bonding fabric materials, hot-melt adhesive web film is often selected due to the need for hand feel, but in fact, as long as the flat film is made thin enough and a softer material is selected, the corresponding requirements can also be met.
Therefore, when manufacturers choose hot-melt adhesive film and hot-melt adhesive web film, they should first test different types and types of products. When the performance meets the requirements or their own expectations, they will make a choice from the perspective of cost performance. . Hot melt adhesive web and hot melt adhesive film are essentially the same.
